// 写页面步骤
// 1. 搭建静态(直接把组件粘贴过来-去"静态组件"文件夹中去找)
// 2. 初始化数据展示
//    先看一下线上的请求,把请求整明白之后,写代码(正常情况下应该去看接口文档)
//    请求:
//
//      {
//        "category1Id": "2",
//        "categoryName": "手机",
//        "keyword": "aa", // 搜索框数据
//        "trademark": "", // 实例: "2:小米"  2是品牌ID  小米是品牌名称
//        "props": [], // 商品属性
//        "order": "1:desc", //  1是综合 2是价格  asc是升序 desc降序
//        "pageNo": 1, // 当前页
//        "pageSize": 2, // 每页条数
//      }
//    2.1 api准备
//    2.2 三连环
//    2.3 mounted调用接口拿数据
//    2.4 展示数据
// 3. 交互
